HARROW-TEETH FASTENING.

SPECIFICATION forming part of Letters Patent No. 265,960, dated October 1'7, 1882.

(No model.)

To all whom it may concern Be it known that I, DANIEL G. HARTUNG, a citizen of the United States, residing at Blair'sto\vn,in thecountyof Benton and Stateof Iowa, have invented certainitew and useful Improvements in Harrow-Teeth Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in fastenings for securing barrow-teeth to the beams; and the object of the invention is the production of an efiicient and durable fastening involving simplicity and economy in construction; and to this end the in vention consists in novel features ofconstruction and combination and arrangementof parts, all as will be hereinafter fully described, and setforth in the claims hereto annexed.

Referring to the accompanying drawings, Figure 1 represents a bottom view or plan of a barrow, showing my improvements asapplied thereto for securing the teeth in position; Figs. 2- and 3, enlarged detail vertical sections, at right angles to each other, through the harrowbeams, fastening, and tooth.

In the drawings, A represents the upper transverse beams, and B the lower longitudi' nal beams, forming the barrow-frame.

0 represents the teeth of the barrow, each one of which is provided with a head-block, D, eastintegral therewith or rigidlysecured thereto, and d at side lugs formed or cast integral with the head-block. These lugs have vertical holes through them for the reception of the fastening-bolts I) b, and extend a short distance above the head-block to form arecess, a, between them for the reception of the lower bar, B, of the barrow-frame, and which is rigidly secured therein by the lugs emhracingthe sides of thebar, and the bolts which pass through said lugs and the upper bar, A, of the frame and secured by the screw-nuts b b.

0 represents a leather cushion arranged intermediate of the bar B and head-block, and it] the recess a, by which jarring of the fastening-bolts is obviated, whereby they are prevented from becoming loose.

The above-described fastening is economical and simple in its construction, while being strong and durable, and giving additional strength to the frame by obviating the punching of holes through the beams for the reception of the teeth and through the lower bars for the reception of the fastening bolts.

Having tints fully described my invention, what I clain as new, and desire to secure by Letters Patent, is

1. The herein-described harrow-tooth, consisting of the body portion 0, having the recessed head-block 1'.) a cast integral orrigidly secured thereto, the side lugs, d 01, east with said block and provided with vertical holes for the reception of the fasteuiugbolts 1), substantially as specified.

2. The combination, with the lower bars, P), attd upper bars, A, having bolt-holes through them, of the teeth 0, each tooth having a headhlock, I), provided with a central recess, a, side lugs, d d, having boltholes through them, and the fastening bolts and nuts, substantially as and for the purpose herein shown and described. Y

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL (J. HARTUNG.
